Question

【题目】Television enables us to see things happen almost at the exact moment ________.

A.which they are happening

B.when they are happening

C.which is happening

D.when they have happened

Answer 1

【答案】B

【解析】

考查定语从句。句意：电视使我们几乎在事情发生的同一时刻看到它们发生。此处moment是先行词，在后面的定语从句中作时间状语，用when引导定语从句，再根据at the exact moment可知动作正在进行，所以用现在进行时态，故选B。
